I have a 3.5" WD Purple HDD I want to have as an external, always-on storage for my surveillance system.
It will connect to my NVR system via eSATA, so I assume a sata-to-esata cable will work just fine for that.
The problem is how do I power it? I think a 3.5" HDD needs both 12v and 5v power via SATA. I was thinking of using a sata to molex adapter, and then powering the molex via mains power with something like this: https://www.aliexpress.com/item/32809227367.html
The problem is that these seem to be low quality, some reviewers have had theirs blow up, and others show the voltages vary a lot (5.8v when it should be 5v). So I don't want to take risks blowing a £100 HDD, even if the adaptors are so cheap.
Does anybody know of a better quality version of these, or a different solution? Hoping to spend <£25 in all.
